A maid (Jeon Do-yeon, Best Actress at the 2007 Cannes fest for Lee Chang-dong’s Secret Sunshine) goes to work in a rich family’s grand house. Maid is seduced by pampered husband. Older housekeeper sees all. Bad things happen. The class warfare in The Housemade feels dated, but there’s something nicely kinky in this lusciously photographed erotic Korean thriller by Im Sang-soo — at least for those who don’t compare it to the far kinkier, out-there 1960 original by Kim Ki-young.
